4th gen 2500 Ram here. Went with the B&W Turnover Ball and their Companion 5th wheel hitch. Totally removable when not in use, returns your bed to completely flat when you take it out. The older model was rated for 16k, but the new one is rated for 20k. They even have a sliding Companion now.

This ^^ in my opinion, best setup on the market. On my second one currently. The first did its job in a rollover accident last winter. Thankfully, the companion hitch is engineered to give way in the event of a rollover, and only then. My truck, with my wife and three young daughters, would have been pulled over along with our fiver had it not given way.
I love having the completely empty bed when needed as well. Just Saturday morning I pulled the hitch out. Took all of three minutes and it comes apart in two pieces so I was able to set it on the floor of my garage on my own.

I have installed fifth wheel hitched in 2 4th gen Rams - the installs aren't bad. Both I did alone in about 2 hours each. There are many options out there but if you are going with a universal rail system, which I use, I recommend Curt brand - they are the exact same mounts as some of the others out there but are generally 15-25% cheaper to acquire. They have custom bracket kits that take out all need for modifications and guess work. I have a Reese 15k Pro fifth wheel and also a 20k goose neck ball on a plate that fits into the universal rails.

For the last year or so I have been considering upgrading my hitch to a double jaw rather than the slide bar type that I have, but what I have works well, just got back from a 1100 mile trek last night with no issues - even through the Pennsylvania mountains and the I95 traffic. Some out there today have rubber torsion blocks to absorb some of the highway bounce that you can get, especially in construction zones and I think that may be a plus. Generally speaking, a very nice hitch is far less expensive than upgrading your pin box.

my 2014 RAM 2500 came with the 5 mount wholes in the box already. The mount frame is a easy removed by to levers on the frame. Reese also makes the frame that drops in the 4 fifth wheel mounts in the box of the truck. I have a 16K Husky hitch that fit the dodge frame in the box perfectly. Have had no problems with my slider.
